NOTICES TO SUBSCRIBERS 



BIRD-LORE is published for the Audubon Societies on the first of every other month by the 



Macmillan Co., at Crescent and Mulberry streets, Harrisburg, Pa., where all notices of change of ad- 

 dress, etc., should be sent. 



Subscribers •whose subscription expires ■with the present issue will find a properly dated 

 renewal blank in their magazine. In the event of a desire not to renew, the publishers would 

 greatly appreciate a postal to that eflect. 



^9~To subscribers whose subscription expired with the issue for December, 1903, and who have 

 as yet neither renewed their subscription nor, in response to our request, sent us a notice to discon- 

 tinue their magazine, the present number is sent in the belief that the matter of renewal has been 

 overlooked. We trust it will now receive prompt attention. 



Complete sets of Volumes I, II, III. IV and V of 'Bird-Lore' can still be supplied. 



Every number of ' Bird-Lore ' is as readable and valuable today as when it was issued, 

 and no bird -lover who is not already supplied can find a better investment than back vol- 

 umes of this mag:azine. Vols. I, III, IV and V are offered at the subscription price of $1 each, 

 postpaid ; the price of Vol. II is $3. 



Entered as second-class mail matter in the Post Office at Harrisburg. Pa.
